I have an Olympus M.Zuiko 40-140/3.5-5.6 ED for sale. The mount is micro 4/3, so it fits the Olympus PEN series of compact digital cameras and other cameras with compatible mounts (Panasonics?).

It's new, with front and rear caps and instruction book but I don't have the original box. It was part of a kit I bought (with a PEN E-PL1 and a 14-45 zoom), but since I already have this focal length range covered I don't need it. I've used it a few times and I've reviewed it on this website, but that's all the use it has seen.

It's very small and very light (6oz) so it makes an ideal travel lens as part of an Olympus PEN outfit.

I'll include a soft carrying pouch.

$150 plus shipping at cost via whatever carrier you choose. Since it's so light I'd expect shipping to be around $5 via USPS.
